Silicon is a semiconductor. It can conduct electricity as well as behave as an insulator by varying it's properties. Silicon is currently the most used material in space semiconductor devices. The conductivity of silicon lies between the conductivity limits of conductors and insulators.
Silicone insulator refers to the use of a layered silicon–insulator–silicon substrate in place of conventional silicon substrates in semiconductor manufacturing, especially microelectronics, to reduce parasitic device capacitance, thereby improving performance. The silicon junction is above an electrical insulator, typically silicon dioxide or sapphire. We supply silicone insulator suitable for electric power.
